Objectives: Intermittent self-catheterization (IsC) improves self-care, independence, body image, and expression of sexuality, reducing the risk of urethral trauma and urinary tract infections. However, increased frequency of catheterization, especially nocturnal catheterization, may disturb the sleep process and reduce the quality of life (QoL). Methods: Sixty patients with spinal cord injury (SCI), 29 of whom were tetraplegic and 65 were paraplegic, were included. The participants were divided into 4 groups based on the bladder drainage types as spontaneous voiding, IsCx4 (4 times a day), IsCx6 (6 times a day), and permanent catheterization. Pittsburgh Sleep Quality Index (PSQI) and Satisfaction with Life Scale (SWLS) were used to assess sleep quality and life satisfaction of the participants. PSQI and SWLS were compared between the groups. Results: The mean age of the patients was 35.06±13.28 years. Median time from SCI was 22 (6-276) months. PSQI and SWLS values were similar among the groups based on the types of voiding (p=0.24, and p=0.68, respectively). In each group, the SWLS and PSQI were correlated with poor life satisfaction and poor sleep quality, respectively. Conclusion: Although we thought that the increased frequency of IsC could affect the sleep quality and life satisfaction, the results of this preliminary study did not support this hypothesis.
